The yellow buoy is 3ft in diameter and weighs 500lbs. It is equipped with a LED flash light antenna that emits a group of 5 yellow flashes every 20 seconds.
The buoy is constantly in motion and can drift up to +/- 600 yrds from its charted position due to the mooring configuration. The mooring line has sufficient slack to allow for various ocean conditions, including big wave events and strong currents.
Buoy sensors are very sensitive.
To keep the buoy operational, please • do not tie to buoy and • avoidfishingwithin600yardsto
minimize entanglement in the mooring line.

Stay Informed!The wave buoy measures wave height, wave direction, wave period and sea surface temperature.
SignificantWaveHeight- The mean wave height of the largest 1/3 waves for a given 30 minute period.Dominant Wave Period - Is the prevailing period with the maximum wave energy. It is measured as the time in seconds between one wave crest to the next wave crest. Average Wave Period - Is the period of all waves during a 30 minute period.Direction - Represents the location from which the wave approaches. 0 degrees represents the North.
Data streaming for the PacIOOS wave buoy is made possible through long-term partnerships between PacIOOS, the U.S. Army Corps of Engineers, and Coastal Data Information Program.
